• 【🔥 PREMIUM HEAT-TREATED ALLOY STEEL】 Constructed from high-grade Silchrome (Si-Cr) alloy steel for intake and Stellite-tipped heat-resistant alloy for exhaust valves. Undergoes rigorous heat treatment and hardening processes to withstand extreme combustion temperatures, prevent warping, and resist wear from high-RPM operation and turbocharged applications (K23A1).
• 【🛢️ COMPLETE REBUILD KIT WITH STEM SEALS】 Includes 16 Premium Viton Valve Stem Seals designed to prevent oil consumption and blue smoke. These seals offer superior resistance to heat and chemical degradation compared to standard rubber, ensuring long-term seal integrity against the valve guide. Everything needed for a complete cylinder head valve job in one box.
• 【⚙️ RESTORE COMPRESSION & ENGINE POWER】 Solves common issues caused by burnt or bent valves: low compression, misfires, rough idle, loss of power, and excessive oil burning. Precision-ground valve faces ensure a perfect seal against the valve seat, restoring factory compression ratios and optimizing airflow for improved fuel efficiency and throttle response.
